An administrator is tasked with horizontally scaling an existing Tanzu Kubernetes cluster from 6 to 4 nodes.
Which action does the administrator need to complete to ensure the cluster scales successfully when updating the YAML definition?

To horizontally scale an existing Tanzu Kubernetes cluster from 6 to 4 nodes, the administrator needs to decrease the number of worker nodes to 4. Horizontal scaling involves adding or removing nodes to the cluster to handle the workload, and since the question specifies reducing the node count, it directly pertains to the worker nodes, not the control plane nodes. Control plane nodes typically have a fixed configuration to maintain cluster robustness and stability, whereas worker nodes are more commonly scaled depending on the required capacity.
B You can't scale in CP https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-7992B7F6-9174-44F4-99BE-C0B5C45FA2EC.html?hWord=N4IghgNiBcIM4GNIFMAECIFc4BdkCcQBfIA
I do like the easy questions. It's B. Let's go over the answers. A. Decrease the number of control plane nodes to 4. - No... control plane? Don't get caught by this one. B. Decrease the number of worker nodes to 4. - Yes, when we talk about horizontal scaling, we talk about how many nodes, when we talk about vertical, that's the size of the nodes (same is true for pods). C. Update the Virtual Machine Class Type. - No... this would be correct if the question asked about vertical scaling, but it doesn't, does it? No, it doesn't. D. Update the Kubernetes version to the latest supported version. - No. This is the silly joke answer.
